The utility model relates to a differential shell casting mold, which includes a runner, a cast-in-place channel, two inner runner groups, a differential shell mold and an inner riser, which is vertically arranged in the middle of the cast in place, and the outlet of the runner is connected with the entrance of the cast-in-place channel; the two internal runner groups are parallel to each other. The middle parts of the two internal runner groups are respectively connected with the cast-in-place channel, respectively, and the two ends of the two inner runner groups are respectively connected with the differential shell mold, and the middle position of the differential shell mould is vertically arranged with an inner riser. The differential shell casting mould of the utility model is set by setting up the runner, the runner, the two inner runner groups, the outer shell mould and the inner riser, and the iron water is introduced by the two inner runner groups, and the hot joints of the castings are made up by the inner riser inside the differential shell mold, which can not only guarantee the densification of the castings, but also improve the quality of the castings. It can also improve casting efficiency and reduce production cost.

一种差速器壳浇注模具
本技术涉及差速器壳铸造领域,特别是涉及一种差速器壳浇注模具。
技术介绍
差速器壳类产品大多为中空的环形铸件,其外侧为法兰,法兰上有较多加强筋,法兰上有一圈环形凸台,由于此环形凸台厚度较厚大,铁水总是最后凝固。现有技术通常采用外侧冒口或顶部压边冒口的方式进行补缩,由于补缩距离偏远,这两种补缩方式很难将铁水补进铸件内部,导致铸件内部易形成集中性孔洞;另外,采用发热冒口进行补缩,补缩效果不稳定,易在冒口下端产生缩松缺陷,容易在加工后暴露出来,该种补缩方式还会降低铸造效率,提高生产成本。
技术实现思路
基于此,本技术的目的在于,提供一种差速器壳浇注模具,其具有结构简单、防止缩松缺陷、提高铸件质量、降低生产成本的优点。一种差速器壳浇注模具,包括直浇道、横浇道、两个内浇道组、差速器壳外模和内冒口;所述直浇道垂直设置在所述横浇道的中部,且所述直浇道的出口与所述横浇道的入口连接;所述两个内浇道组相互平行设置在所述直浇道的两侧,所述两个内浇道组的中部分别与所述横浇道连接;所述两个内浇道组的两端分别连接有差速器壳外模,所述差速器壳外模中间位置竖直设置有一内冒口。本技术的差速器壳浇注模具通过设置直浇道、横浇道、两个内浇道组、差速器壳外模和内冒口,利用两个内浇道组引入铁水,并通过内冒口内置于差速器壳外模中对铸件热节进行补缩,既保证铸件的致密性,提高铸件质量,又能提高铸造效率,降低生产成本。进一步地,所述两个内浇道组均包括两条相互平行的内浇道,所述内浇道的两端分别连接有一差速器壳外模。进一步地,所述直浇道为圆筒形。进一步地,所述横浇道与所述直浇道的连接处的两侧设置有过 ...
